Principle Of Touch Table Lamp

Date:Mar 05, 2020

The principle of the touch table lamp is to install an electronic touch IC inside, and form a control loop with the electrode sheet at the touch of the table lamp. When the human body touches the sensing electrode sheet, the touch signal is transmitted to the touch sensing terminal by the pulsating DC power, and then the touch sensing terminal will send a trigger pulse signal to control the light on; when touched again, the touch signal will be pulsed The direct current generates a pulse signal and transmits it to the touch sensing terminal. At this time, the touch sensing terminal will stop sending out the trigger pulse signal. When the alternating current crosses zero, the light will go out naturally. However, sometimes it may light up after power failure or unstable voltage. If you touch the paper or cloth with excellent sensitivity of the received signal, it can be controlled.
